The budget carrier on Monday (26 July) posted a €273 million (£234 million) net loss for the three months to 30 June, down from €185 million (£158 million) during the same period last year.
Boss Michael O’Leary said Covid-19 was continuing to "wreak havoc" on business, citing the cancellation of "most" Easter flights and a "slower than expected" easing on EU travel restrictions.
O’Leary said "significant uncertainty" around travel green lists, particularly in the UK, and "extreme government caution" in Ireland had ensured the majority of Q1 bookings were "close-in" and sold at low prices.
